Figure 4. Mucus secretion analysis in conjunctival tissue. A: Periodic acid-Schiff (PAS) staining in slides of vehicle (upper) and azithromycin (lower). Azithromycin showed a reduction in mucin secretion (purple) compared with vehicle-treated animals. Magnification: 40X. B: Results obtained for measurements performed in PAS-stained sections. Data are represented as meanĀ±standard error of mean (SEM). Four eyes per group were included. All data were analyzed with SPSS 15.0 software. (*p<0.05 versus vehicle)
